Abstract: In accordance with the relevant historical data and the restoration forest resources data, the status of Korean pine primitive forest before destruction in Maoershan experimental forest farm was analyzed. This forest was dense and the amount of growing stock was about 300 m³/ha, this primary forest experienced the regime establishment and change, but was protected and developed due to sparse population, low levels of productivity. In 1896-1945, the forest was destroyed by the predatory logging of Czar Russia and Japanese militarists. The primary forest was wiped and razed to the barren ridge with only 54.9 m³/ha forest maintained. In order to change the status, and make the rapid recovery of forest resources, forest workers took the restoration ecology theory as the basis to make a comprehensive survey, adjust the structure, and introduce the Korean pine populations in 1958. After 50 years, the mixed needle-deciduous forests were established, the restoration effect was significant.
